How to return a specific status code and no contents from Controller

Question

I want the example controller below to return a status code 418 with no contents  Setting the status code is easy enough but then it seems like there is something that needs to be done to signal the end of the request  In MVC prior to ASP NET Core or in WebForms that might be a call to Response End   but how does it work in ASP NET Core where Response End does not exist   public class ExampleController   Controller        HttpGet  Route   example main        public IActionResult Main                 this HttpContext Response StatusCode   418     I m a teapot            How to end the request             I don t actually want to return a view but perhaps the next            line is required anyway          return View
